 ### Added
 
 - Added configurable harness session context entry transforms and custom-entry message projectors.
+- Added custom metadata support in JSONL session headers ([#6417](https://github.com/earendil-works/pi/pull/6417) by [@ArcadiaLin](https://github.com/ArcadiaLin)).
 - Exported `InMemorySessionStorage` and `JsonlSessionStorage` ([#6435](https://github.com/earendil-works/pi/issues/6435)).
 
 ### Fixed
 
 - Fixed harness split-turn compaction to serialize summary requests so single-concurrency providers are not asked to run overlapping generations ([#5536](https://github.com/earendil-works/pi/issues/5536)).
+- Fixed harness tool calls from length-truncated assistant messages to fail instead of waiting for missing tool results ([#6285](https://github.com/earendil-works/pi/pull/6285)).
+- Fixed harness session ingestion to normalize `null` message content before context projection, avoiding crashes on lax imported transcripts ([#6343](https://github.com/earendil-works/pi/pull/6343)).
+- Fixed non-positive or oversized harness shell execution timeouts to fail with a clear validation error instead of being clamped to an immediate timeout ([#6181](https://github.com/earendil-works/pi/issues/6181)).
 - Fixed harness session storage short entry ids to use the random tail of the generated uuidv7 instead of the timestamp prefix, which was nearly constant between calls ([#6242](https://github.com/earendil-works/pi/issues/6242)).
